SMQ1,SMQ2,SMQR,SMQS
SMQR:Registration of Inbound Queues (BI,R3)
SMQS: Registration of Destinations (R3,CRM,BI)
SMQ1:qRFC Monitor (Outbound Queue) (R3,CRM,BI)
SMQ2: qRFC Monitor (Inbound Queue) (R3,CRM,BI)
SMOHQUEUE : Replication & Realignment Queues (CRM)
Stop R3
1. Stop queue R/3 smqr ,smqs
2. Stop queue CRM&BW smqr ,smqs
Stop CRM
1. Stop queue CRM smqr ,smqs
2. Stop queue R/3 smqr ,smqs (for CRM)
Stop BI
1. Stop queue BW smqr ,smqs
2. Stop queue R/3 smqr ,smqs (for BW)
Start R3
1. Check q hold smq1 R/3 In case of smq1 use lock all queue ( status of queue change to STOP)
2. Start queue R/3 smqr ,smqs
Start CRM
1. Start R&R start SMOHQUEUE
2. Start queue CRM smqr ,smqs
SMQ1:Out bound queue which is phisical storage of OUT bound delta(RSA7:delta queue),delta data will be saved in unstructured format
SMQ2:Inbound queue,Where you can see data which is coming from other systems to your
R3 system
SMQS:QOUT scheduler where u can see the queue names which are connected to your R3 system like BI snd someother systems which are geeting data from your R3 system
SMQR:QIN sheduler where you can see the queues which are connected to your R3 system and from which you are pulling data to you R3 system like CRM for example your R3 system is getting updates from CRM system then CRM queue u can see in SMQR scheduler
While upgrading your source system all systems will be cleared because Upgrade will be fast and u can avoid data corruptions.
somtimes data source structure will be changed because of upgrade ,so if u keep delta data it will be corrupted and u will face delta load will failed and u will get dumps in RSA7 and to currect this error u have to delete delta data nd reintilize.
to avoid above errors ,we have to clear delta data before upgrade.if u do this u will not miss any delta data and upgrade also will be fast.
